9. Modbus TCP

9.1. Overview

The OPT-3-MTPEG-IN device operates as a Modbus TCP to Modbus RTU converter and communicates to the drive using the
Modbus RTU protocol. For drives with factory fitted interface, the operating principle remains the same.

9.2. Usage Requirement

 When using the Modbus TCP to control the drive it is necessary to ensure that the amount of data and frequency of data exchange
does not exceed the amount of data which can be successfully exchanged on the Modbus sub-network within the permitted time.
 Whilst the Optitools Studio PC software supports communication through the Ethernet network for device commissioning, it is not
recommended to use this continuously during operation of the drive as the additional communication load may exceed the limit
resulting in loss of Cyclic communication.
o In this case, connect the PC software to the drive serial port using the USB / RS485 adaptor.
 Use port D1 or D2 of the external Ethernet adaptor. Use port D1 or D2 of the external Ethernet adaptor.
 Use port D1 or D2 of the Compact 2 Ethernet adaptor. Use port D1 or D2 of the Compact 2 Ethernet adaptor.
 Use one of the available ports labelled "IOIOI". Use one of the available ports labelled "IOIOI".
o Do not connect via Ethernet if data logging is required. Do not connect via Ethernet if data logging is required.
